Type of memory | Description |
|---|---|
Volatile memory | The printer uses standard random access memory (RAM) to buffer temporarily user data during simple print and copy jobs. |
Non-volatile memory | The printer may use two forms of non-volatile memory: EEPROM and NAND (flash memory). Both types are used to store the operating system, printer settings, network information, scanner and bookmark settings, and embedded solutions. |
Hard disk memory | Some printers may have a hard disk drive installed. The printer hard disk is designed for printer-specific functionality. The hard disk lets the printer retain buffered user data from complex print jobs, form data, and font data. |
Erase the content of any installed printer memory in the following circumstances:
The printer is decommissioned.
The printer hard disk is replaced.
The printer is moved to a different department or location.
The printer is serviced by someone from outside your organization.
The printer is removed from your premises for service.
The printer is sold to another organization.
Degaussing—Flushes the hard disk with a magnetic field that erases stored data
Crushing—Physically compresses the hard disk to break component parts and render them unreadable
Milling—Physically shreds the hard disk into small metal bits
